One Bio, Two Metrics

Finger vein, print scanner on the same sensor (Engineering News - South Africa)

The device maps the minutia of a person’s fingerprint, as well as the vein network in the second phalanx of the same finger. The company’s algo-rithms then compare the results with a database, either using the data to identify a person as belonging to a group, for example employees or technicians, or to verify a person’s identity when used in conjunction with cards, personal identification numbers and common security measures, which improves security and reduces the likelihood of fraud.

Two modalities on the same sensor and using the same body part, neat.
